Many people sit on chairs and cross their legs habitually, thinking this is more comfortable. But experts warn that crossing your legs may cause many diseases.

Disease 1: It may cause varicose veins or thromboembolism in the legs. Liu Deping, deputy director of the Department of Cardiology at Beijing Hospital, said in an interview with reporters that when the legs are crossed, the padded knees are compressed, which can easily affect the blood circulation of the lower limbs. Keeping your legs in the same position for a long time can easily cause numbness. If the blood circulation is further blocked, it is likely to cause varicose veins or thromboembolism in the legs. "Especially for the elderly who suffer from high blood pressure, diabetes, and heart disease, crossing their legs for a long time will aggravate their condition." Liu Deping suggested that when you feel numbness or soreness in the muscles of your legs, you should immediately lay them flat and rub or pat them repeatedly with your hands. To relieve fatigue and restore blood flow as soon as possible.

Disease 2: Affects male reproductive health. "Developing the habit of crossing one's legs is very detrimental to reproductive health." Li Hongjun, chief physician of the Department of Urology at Peking Union Medical College Hospital, said that when crossing one's legs, the legs are usually clamped too tightly, which increases the temperature of the inner thighs and around the genitals. For men, this high temperature can damage sperm, which may affect fertility in the long term. For this reason, Li Hongjun suggested that you should not cross your legs for more than 10 minutes, and avoid crossing your legs too tightly. If you feel sweat oozing out from the inner thighs, it is best to walk in a ventilated place for a while to dissipate heat as soon as possible.

Disease 3: Causes spinal deformation and back pain. Gao Xinsheng, an orthopedic surgeon at Beijing Hospital, said that the normal spine of the human body should be in an "S" shape when viewed from the side, but it is easy to stoop when the legs are crossed. Over time, the spine will form a "C" shape, resulting in uneven pressure distribution between the lumbar and thoracic vertebrae. If things go on like this, it will also compress the spinal nerves and cause back pain.

In addition, experts also suggest that people who sit for a long time should maintain a correct sitting posture and cross their legs less often. If you can't change it for a while, don't cross your legs for too long. Change your sitting position after a few minutes, or stand up and stretch your muscles after an hour.

The Origin of Erlang Legs

The poet Liushahe once wrote an article "The Explanation of Erlang Legs", which interestingly explained the origin of Erlang Legs. He pointed out: Erlang's legs are not only said in Sichuan Province, but also in other provinces. This is the sitting posture of Erlang Shen. The statue of Erlang in the main hall of Chuanwang Temple in my hometown, and the old statue of Erlang in Erwang Temple in Jiangyan, Dudu, Shu, are all like this. It is said that Erlang was the second son of Li Bing, the governor of the Qin Dynasty. He helped his father cut off the pile and kill the dragons to eliminate the harm. After his death, Erlang was granted the title of God.

In "The Romance of the Gods", there is the Erlang God Yang Jian, who was turned into a novel from a legend, which is even more absurd... The sitting posture of Erlang God is definitely not in line with Confucian rules. The so-called cross-legged posture, in technical terms, should be the Yu step.

According to legend, Yu was trying his best to control the floods and clear the ditches. However, he did not enter his house for ten years and suffered from hemiplegia (hemiplegia). One of his legs became stiff and he became lame. When I was young, I saw a wizard doing a dance, jumping with one foot and lifting up with the other. It was called Yu Step, which was imitating Yu. The statue of Erlang in Dujiangyan is made into a sitting position with his right leg resting on his left leg, also imitating Yu. In the 1980s, it was reshaped into a standing posture, holding a spade and two legs, and the sense of mystery was completely lost. The old sculptures retain the tail of ancient myths, which shows where we come from, and it can be regarded as respecting the ancient culture. Changing it into a migrant worker repairing water conservancy makes the term "erlang legs" lose its validity and makes it difficult for future generations to examine it. It is really not worth it.
